Flames engulfed an 18-wheeler in Northport Tuesday afternoon, snarling traffic at the intersection of Lurleen Wallace and McFarland Boulevards.

It was not immediately clear what caused the inferno or if anyone was hurt, but the blaze was extinguished by the Northport Fire & Rescue service just after 7 p.m.

Traffic spotters snapped a picture and sent it to Townsquare Media's Cap Ray, who you can follow on Twitter and Instragram for daily updates on traffic conditions in the Tuscaloosa area.
